JetBlackDragon, please edit your posts using the "edit" function under the "options" tab to the lower right of every comment, instead of making a new thread for the same draft. I just locked your duplicate thread.

Kudos for reading the guides and going through the sandbox and forums first; that alone saves you a lot of getting fussed at.

As for the idea, though, I'm not seeing a keeper here: Its a thing in a gas mask that apparently knows SCP-049, the end. I strongly suggest doing some browsing of high rated series III articles, and doing another round or three of brainstorming afterwards. You might also try something non-humanoid for your first scp.

On the technical side:

Punishments in the containment procedures are something that people fondly roll their eyes at in series I articles. In the modern foundation, it is to be assumed that you don't have to tell trained professionals not to do stupid things with potentially world-destroying anomalies.

The description is also rather disjointed. It reads like you were writing this off the top of your head and adding random attributes as they occurred to you. Its important to have a logical organized flow to how you present information.

The wording is rather clunky and unprofessional-sounding in places, and that is a critcal part of writing a SCP. Reading things you write out loud to yourself afterward can be an excellent way to proofread, I'd strongly suggest trying it on your next attempt.
